"Thick" accumulates thin hair, and the spirit "picks" flying! Sany 1202S new generation of medium and thick coal seam shearer is coming!

In 2022, Sany Heavy Equipment will be newly launched1202S SmartShearers。 This series of shearers has been upgraded in an all-round way in terms of reliability, matching, adaptability, and intelligenceThe center of gravity of the whole machine is "lower", the traction speed is "faster", the traction power is "greater", and the climbing ability is "stronger"！

High reliability

1.1 Rocker Arm

· The shell material is upgraded, the strength and wear resistance are increased by 30%, and the service life is ≥ 8 years.

· The transmission system runs smoothly and reliably, with low temperature rise.

1.2 Rollers

· The tail of the blade is made of thickened alloy wear plate.

· Optimize the arrangement of picks, reduce the cutting impedance by 30%, and increase the coal loading effect by 25%.

· Alloy bean picks, 10,000 tons of coal consumption ≤ 8.

1.3 Walking section

· High-quality alloy cast steel + quenched and tempered, the strength is increased by 30%.

· Hydraulic nut coupling fastening.

1.4 Travel wheels

· Optimized tooth profile, meshing pressure angle ≤ 20°.

· The hardened layer > 5mm, and the life span ≥ 8 months.

1.5 Guide Skates

· Waist-shaped hole design for improved adaptability.

· Casting material upgrades.

· Tungsten carbide wear plate hardness ≥ 67HRC.

1.6 Splined shaft

· 40CrNiMo+ is high-profile, and the intensity is increased by 30%.

Good matching

· 800 scraper as standard.

· The single-row wheel walking part can be equipped with 764 scraper.

· It is equipped with a bending rocker arm as standard, and the coal loading effect is good.

Adaptable

· Accommodates large inclination angles of ≤ 45°.

· It can be adapted to ≤ 35° large plunge.
